SWITCH STAND.

Application filed April 27, 1225.

To @ZZ 't0/lem t muy concern.

Be it known that l, l.losnrrr FHILANDER Hasn', a citizen of the United States, residingl at San Diego, in the county of San Diego and State of California, have invented a new and useful Switch Standpof which the following,` is a specification.

This invention aims to provide a novel switchy throwingi mechanism whereby a signal will be given when a train runs through a switch without having the switch points set properly. The invention aims, further, to provide novel means for operating the switch points. A. further object of the invention is to provide a device of the class described which will withstand severe use, and be so constructed that its operation will not be interfered with appreciably by snow or ice.

lt is within the province of the disclosure to improve generally and to enhance the utility of devices of that sort to which the invention appertains.

llVith the above and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being` understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings z- Figure 1 shows in top plan, a device constructed in accordance with the invention;

Figure 2 is a side elevation;

Figure 3 is a vertical section wherein parte appear in elevation;

Figure l is a bottom plan of the switch stand;

Figure 5 is a section taken about on the line 5 5 of Figure 4; and

Figure 6 is a sectional view showing the bracket on the switch stand.

The numeral 1 marks the main line rails of a railroad track, the siding rails appearing at 2, the switch points at 3 and the switch ties at il. The switch points 3 are operatively connected in the common way by a bridle 5 which is pivoted at 6 to a link 7.

The numeral 8 marks a switch stand including a base 9 and a pedestal 10 upstanding from the base, the base being secured at 11 to the switch ties t. In the base 9 of the switch stand V8 and in the pedestal thereof, a

Serial No. 26,206

vertical shaft 12 is liournaled, the shaft being L pped at lower end with a crank arm 14;. including` an upstanding portion. The b. Q of the switch stand is provided with a raised lower surface 15, there being re cesses 16 extended inwardly from opposite e-.fuz'es of the buse 9 and interrupting; the said face 15, as indicated in Figure i of the c awings. Vlfhe inner end ofthe link 7 is mounted on the upstandingr portion of the crank arm 11i of the shaft 12. rlhe upstanding portion of the crank arm lll terminates so close to the lower surface 15 of the hase 9 of the switch stand that, when the crank arm 14 isso disposed that the switch points 3 are set either for the main line or for the siding, the inner end of the link 7 cannot escape upwardly off the crank arm. llVhen, however, the crank arm 1li is so disposed that the upstanding portion thereof is beneath one of the recesses 16, the inner end of the link .7 may be mounted readily on the upstanding portion ofthe crank arm la. The device, therefore, is so constructed that it affords means whereby the link 7 may be assembled readily with the crank arm 11i, and whereby, when the device is in use, the link will remain securely assembled with the crank arm.

The numeral 17 marks a disk-like keeper having' any desired number of notches or sea-ts 18 in its edge, there beine,` a stop pin 19 in the upper surface of the keeper, adjacent to each notch. The shaft 12 extends through the keeper 17. The keeper 17 has a downwardly and outwardly extended angular arm 20 movable in a bracket 21 secured to the pedestal 10 of the switch stand 8. A, keeper 1T and its arm 20 ordi narily are lined with respect to the switch stand 8, because the bracket 21 carries a shear member 27, `engaging; the arm 20, the shear member beinp; weak Vcnouejh so that it can be broken under extraordinary conditions which will be alluded to hereinafter. @n the outer end of the arm 20 there is a standard 22 carrying; a day signal 23, the standard terminating; at its upper end in bifurcations 2li carrying,` translucent colored screens 25 disposed on opposite sides of a lamp 26 mounted on the upper end of the shaft 12. l

rEhe numeral 28 designates a casing or support which is secured at 29 to the shaft 12, the casing or support being disposed i1nmediately above the keeper l?. In its under portion of the casina` a8.

surface, the casing` 28 has a `a'roove 4t2, wherein the stop pin 19 is received when the casing` 28 is rotated with respect to the keeper 17. rlhc numeral designates a latch, in the tori ot a lever, pivoted or tulcrumed at 31 on the casing` 28. the latch having' an arm wherein there is an opening;` adapted to receive a lock 311 secured bv a chain 35 or other rise to an;7 accessible lllhen the latch leve 30 is swuna downwardl);7 into the notch or seat- 18 oit the n 17, and when the lock is mounted in the openingl 33 of the lat-ch lever, the latch lever cannet` be siming` upwardly out et the notch 18, and the switch mechanism is locked in an).7 position to which it mayv have been set. lllhen the lever 3() is swung upwardly but of the notch 1S in the keeper 1.7, then the casing` Q8 and the shaft 12 may be rotated, the crank arm 14 on the lower end of the shaft 12 operating through the to more the switch lfeepor link 'i' and the bridle o points 3.

The screens normally stand parallel to the track, se that thef,7 will not obscure the lamp QG with respect to a train which is moving along` the track. lt a train enters the switch when the switch is closed, and toi-ces or splits the switch, then the shaft 12 will be rotated forcibly, through the instrumentalityv et the bridle the link 6 and the crank arm 14 on the shaft 12. rThe keeper 1t will rotate with the casi e; 28 and the shaft 12, because the casing` 28 is coupled to the keepe 17 b v means o" the latch 30. lllhen the keep-i` 17 is tercibl;7 rotated, as aforesaid, the shear member 27 will break, and no damage will be done to the mecha nism. lVhen the keeper 17 is rot-ated, the arm 2O and the standard 22 will be swung, thereby disposing the screens 25 crosswise with respect to the track, the screens so altering; the color ot the light proceeding,A troni the lamp 26 that a person on an approaching train will be admonished at once as to what has taken place with respect to the switch points.

The device 'forming` the subject matter et this application is sate, simple and durable, positive in action and always ready tor use. l't is so constructed as to obviate 1nan7 et the delays which are encountered in the moving` ot trains. rlhe general construction of the device is such that the point of connection between the crank arm 14 and the link 7 is well protected trom sleetand snow. lt is to be observed that the pedestal 1() does not rise from the base plate 9 at the geometrical center of the base plate. Consequentlv, when the switch stand is mounted in place, as shown in Figure 1, there will be l v n l 1- Y a U L, t ,J4-(.1 t' i A L amy-,e Loem Jem. n Lne switon les the bridle 5 and the link T to work.
